Personally I love Death Track Revelation, it was one of the first games I purchased via Steam and Post Apocalyptic Mayhem (P.A.M.) is a lot of fun with its vehicular combat. P.A.M. also has one dlc available, but I don't think it's included with the bundle. At the moment it has 75% off and costs £0.49 (approx $0.65). Clutch is a AAA title as is Crash Time 2,is a AAA game that has excellent graphics, with vehicles and environments that look pretty good. The dialogue in Crash time 2 is a little naff, but the game is excellent. As for Wastland Angel, I've always found top down vehicular games a little harder to play. The saving grace with this one (for me at least) is the vehicular combat. If you like killing zombies, then clutch is your game. Metal Drift is a futuristic arena combat game using vehicles. something akin to a futuristic demolition derby.
